They have met twice before. They are 1-1. Their most recent match was in February and saw Zverev win in 2 tie break sets.
What was Isner doing in the last round?? It was an awful performance from the American against Zverev. Zverev broke serve in the very first game but Isner broke back and looked more settled. Then a weak service game handed Zverev the set. I have similar thoughts about today’s match that I had before the Isner one. There were signs last week that Zverev was mentally tired.
Cilic reached the semi finals last week. He won the title in Cincinnati in August. If Cilic can serve well and give very few break chances I think Zverev will get frustrated.
Wait for 1.90 on Cilic in set 1
